Yes, see one my previously posted message regarding Windows behaviour.

Thanks that's appreciated.

You got me puzzled there, can't remember an attached email, but then again
I sometimes forget to set the mail to plain text instead of html.
> 2) Have you compared tgt performance with IET recently?
I did a quick test just now, very interesting. Running tgt/iet on same 
machine as open-iscsi
I noticed that iet is nearly twice as fast. I used a simple test (just 
hdparm -t) but the
difference in behaviour is striking. tgt keeps returning the same speed 
using hdparm, while
iet creeps up in speed (which was initially faster anyway) to six times 
faster than tgt.
Mind you that must have something to do with caching, it's just strange 
that tgt doesn't show
that behaviour.
